Ancylidae are a taxonomic family of small, freshwater, air-breathing limpets. In other words they are aquatic pulmonate gastropod mollusks.

These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or "pseudobranch" which can serve perfectly well as a gill when they are unable to reach the surface for air.
